Abstract

1,216,628. Mixing liquids in proportions. BERG & BURG N.V. 4 June, 1969 [6 June, 1968], No. 28149/69. Heading B1C. [Also in Division B8] In an apparatus for diluting a concentrated salt solution with soft water in a predetermined ratio to form a dialysate the concentrate is pumped from a tank 11 by a centrifugal pump 10 through a conduit 9, 12 into a mixing vessel 1 until it reaches a tubular electrode 6 surrounding the glass inlet pipe 5. The pump 10 is then stopped by the controller 40 and excess concentrate siphons back through the pipe 12, 9 and pump 10 until an amount determined by the position of the lower end 7 of the vertically adjustable pipe 5 remains in the vessel 1. Soft water is then admitted by valve 14 to the tangential inlet pipe 13 and liquid rises in the vessel 1 and siphon leg 15a until it reaches electrodes 19, when valve 14 closes and the mixture is automatically siphoned from vessel 1 into the secondary mixing vessel 18 which has a mechanical stirrer 20. When this is full it is discharged by automatic siphon 21 with a storage 'tank 22, which is discharged by a pump 26 having a by pass 29 with a regulating valve 30. Operation of the apparatus may be controlled by demand as sensed by liquid level electrodes 48, 49 in the tank 22. The secondary mixer 18 has a bleed tube 24 to ensure complete discharge; the remaining conduits are vent pipes and flushing lines.
